Abstract

The utility model discloses a detector for pressing pain which comprises a sleeve 1, a piston 2, wherein the piston 2 is arranged inside the sleeve 1, and the lower end of the sleeve 1 is connected with a bark pocket 3, while the upper end is connected with a pressing stalk 4. The sleeve 1, piston 2 and the bark pocket 3 form a closed space which is full of fluid. The pressure spring 5 is arranged between the pressing stalk 4 and the piston 2, and the sleeve 1 is provided with a scale. With the utility model, the result of the pressing pain test is uniformity and precise.

Description

A kind of tenderness analyzer

This utility model relates to a kind of Medical Instruments of measuring tenderness.

Pain is the common sympton of numerous diseases, its form of expression mostly is tenderness greatly, pressurized produces pain, the state of an illness that the quantitative analysis of tenderness is helped accurately to understand patient, at present, measurement to tenderness does not still have the recognized standard and method, in the patent No. is that 97246126.4 technology has proposed a kind of measuring method and instrument, its structure comprises sleeve, indicate graduated push rod and be enclosed within stage clip on the push rod, the push rod front end connects rigid contact, and its metering system is for measuring the pressure that diseased region can bear.Analyzing this patent can find, if be applied to the clinical and scientific research of pain research, there are many incomplete places in this technology.

Human body has particularity to the conduction and the strain of power, and in most of the cases, pressure pain point is positioned at bone surfaces such as apophysis, and diseased region is not to be identical everywhere to the sensitivity of pressure, and the value that records often depends on wherein to the most responsive part of pressure.Diseased region should be considered to a stereochemical structure with definite shape and volume and or the zone, should fully take into account the distortion that human body produces when measuring tenderness and produce thus under certain pressure measuring and the influence of pain sensation impression, such as fat and thin, its result often differs greatly, because thin body's subcutaneous tissue is poor, when the contact of measuring instrument acts on the apophysis surface with the form of rigid face, power can not act on diseased region uniformly, weaker possibly and make the value that records less to the toleration of power, and thicker subcutaneous tissue such as fat are cushioned strength and disperse, the practical function area of power increases, pressure reduces, thereby makes the value possibility that records bigger than normal.

We think, the generation of tenderness is not the size that depends on the pressure that acts on diseased region, and determine in the size of pressure, and the size of its value depends on the ability to bear of the sensitive portions of pressure to pressure, such as, the pain sensation that is produced when identical power presses on diseased region with the contact of different area obviously is different, if gaging pressure only, when different parts is measured, because contact area may be different, thereby make the comparability of measurement result relatively poor, even for same position, for different people, the comparability of measurement result also is relatively poor.

The purpose of this utility model is to provide a kind of and tests pressure, tests evenly tenderness analyzer accurately.

This utility model is achieved in that a kind of tenderness analyzer, comprise sleeve, piston, piston places in the sleeve, the connection of telescopic lower end is provided with leather bag, the upper end connects press handle, forms the space of sealing between sleeve, piston, the leather bag, is full of fluid in this space, between press handle and the piston stage clip is set, sleeve is marked with scale.

Operation principle of the present utility model is based on the equal strength transport properties of liquid for pressure, during use, leather bag contacts with tested position, in the pressing force quantitative changeization that applies, leather bag is also corresponding to deform, the area that contacts with tested position changes, make pressure can act on tested position uniformly, what hold in the leather bag is fluid, push the come down to pressure of strength conduction at tested position, speak of in description of the Prior Art, utilize the pressure test more to meet the characteristics of tenderness test, test result is more accurate.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done further detailed description:

Fig. 1 is this utility model cutaway view.

Fig. 2 is this utility model user mode sketch map.

As shown in the figure, piston 2 places in the sleeve 1, the connection of sleeve 1 lower end is provided with leather bag 3, the upper end connects press handle 4, forms the space of a sealing between leather bag 3, piston 2, the sleeve 1, fill fluid in this space, in the sleeve 1 between piston 2 and the press handle 4 stage clip 5 is set, labelling pressure, two kinds of scales of pressure on the sleeve 5 for convenient indication, are provided with pointer 6 on the piston 2.

Use principle of the present utility model is as follows: place skin surface with leather bag 3 ends, the tester pushes press handle 4, leather bag 3 compressive deformations, and as shown in Figure 2, the fluid in the leather bag 3 rises, and pointer 6 indicates the size of pressure and pressure.Use this device to test tenderness, test is even, and test result is reliable and stable, can not produce false pain owing to pressure is uneven, can be used for the comparison of tenderness between the comparison of tenderness between same patient's different parts and different patient, can fully satisfy scientific research and clinical needs.
